Now the oil press has perfected the conditions of power, pressure and temperature, so it is very easy and convenient to work. First, the raw materials are screened and impurities are removed, then the raw materials are crushed and about 7-8% of water is added to soften them, and then steamed in a steamer to 115 degrees. It can be squeezed from left to right. Oil pressing is divided into cold pressing and hot pressing. In order to improve the oil yield and the quality of oil products, hot pressing is generally used. The two process flows are as follows:

Cold pressing: rapeseed - screening - embryo pressing - pressing. First, screen the rapeseed to remove impurities, and then check the moisture content of the rapeseed. If there is no testing equipment, you can use the local method to test: use your fingernail to squeeze the rapeseed. If there is any sound, , and divided into two pieces, or if oil is squeezed out, it is most suitable. If it becomes powder, it will be too dry, and if it forms a cake, it will be too wet. If it is too dry, add 2.5-3% water, stop for a while, and directly enter the oil press for squeezing. Just squeeze it twice.

Hot pressing: raw materials - screening - embryo pressing - steaming and frying - pressing. The rapeseeds are screened to remove impurities, and then enter the embryo rolling machine to roll the embryos. After rolling the embryos, they enter the steaming and frying pan for steaming and frying. During the steaming and frying process Add 2-3% water into the pot, and wait until the fried seeds reach a brown color and the temperature is 110 degrees to 120 degrees, then they can be squeezed.

Palm Oil Press

Palm fruit after digesting enters into screw oil expeller for palm oil pressing. Huatai patented palm fruit oil press has a processing capacity of 2-20TPH. This series of products is fully automatically controlled by PLC. The hydraulic system controls the cake discharging, which effectively reduces the residual oil in the cake and the core crushing rate. The spiral body and pressing cage are strong and have high service life long, the equipment operates stably.

After palm oil pressing, our machine divide oil palm fruit into two parts, the mixture of oil, water and solid impurities, and the press cake (fiber and nut). The pulp stone separation obtained CPO and stone, palm oil press machine adopts the double screw helix continuous discharge and hydraulic, greatly improving production efficiency.
